Yes – Photovoltaics are worthwhile for industrial and commercial businesses In most cases, it is economically and strategically beneficial. Companies can significantly reduce their electricity costs, hedge against rising energy prices, and simultaneously meet regulatory and ESG requirements.
Photovoltaics is particularly economical when:
- one High power consumption during the day consists of
- large Roof or open areas available
- Electricity prices long-term above ~10 ct/kWh
- (e.g., through load management or storage) can be optimized
What are the concrete benefits of photovoltaic systems for businesses?
Photovoltaics offer industrial and commercial businesses several measurable advantages:
Economical
- Reduction of electricity costs through self-supply
- Predictable energy costs for over 20 years
- Protection against rising electricity prices
- Additional revenue from feed-in or direct marketing
Strategic
- Independence from the energy market
- Relief with certifications for Sustainability & ESG
- Competitive advantages with customers and investors
Technical
- Decentralized energy supply increases supply security
- Increase photovoltaic self-consumption through memory
- Integration Energy management systems possible
What types of photovoltaic systems are there for industry and commerce?
1. Battery Systems (Standard Solution)
Large commercial and industrial roofs are ideal for Photovoltaics on roof surfaces especially to:
- Use of existing roof surfaces
- Economically, the first choice in most cases
- Quickly achievable
- Enhances the property
- operates the Photovoltaic obligation
2. Open area facilities
Solar parks are extremely profitable, highly efficient, and make perfect use of fallow or buffer areas for their own electricity production.
- For companies with available land
- High performance possible
- Especially relevant for energy-intensive companies
3. Solar Carports
Solar carports deliver high yields due to their flexible orientation, can also cover loading ramps or outdoor storage areas, and are already mandatory in some federal states.
- Dual use of parking areas
- Combination with charging infrastructure possible
4. Facade-PV (BiPV)
Building-Integrated PhotovoltaicsBuilding-integrated photovoltaicsreplaces conventional building materials like bricks, glass, or facade panels with solar modules.
- Supplement for limited roof areas
- Architecturally integrable
- Not always economical, but increasingly relevant
How is a PV system correctly sized for a company?
The optimal system size is primarily determined by electricity consumption:
- The goal is usually a high internal consumption (>60–80 %)
- Oversized facilities → more feed-in leads to lower profitability today
- Too small facilities → unused potential
Key influencing factors:
- Load profile (day/night, weekly trend)
- Available area
- Power connection situation
- Future developments (e.g., electromobility, heat pumps, production expansion)
This is precisely where professional planning creates the greatest added value in practice.
What role do storage and energy management play?
Without energy management, a lot of potential remains untapped.
Battery storage
- Increase the Photovoltaic self-consumption
- Reduce peak loadsPeak Shaving)
- Can generate additional revenue (e.g. Control energy or to Power trading)
Load management
- Shifts consumption to PV generation timesLoad shifting)
- Reduces grid fees
- Stabilizes operation
Energy Management Systems (EMS)
- Connect generation, consumption, and storage
- Automated Optimization
- Foundation for the economical operation of larger systems
What grants and models are available for businesses?
In practice, fewer classic subsidies are crucial – but Financing and Operating Models:
Typical models:
- Capital Expenditures (CAPEX)
- Contracting / PPA (OPEX)
Electricity procurement without own investment - Rental or leasing models
Depending on the company, particularly Contracting to be interesting, as:
- no capital commitment arises
- Risks can be outsourced
- Planning and operation are carried out externally
What are the biggest challenges - and how can they be solved?
High initial investment
Solution: Contracting, PPA, or financing
Limited Areas
Solution: Combination of roof, carport, facade
3. Complex Regulation
Solution: Structured Project Development and Energy Economic Evaluation
4. Integration into the energy system
Solution: Energy Management + Storage + Load Optimization
When is photovoltaic NOT worthwhile?
Photovoltaics aren't always automatically sensible.
- very low daily power consumption and no external consumers to whom the surplus can be sold
- heavily shaded or unsuitable areas (lack of structural integrity, roofs in need of renovation, high air pollution, etc.)
- extremely low electricity prices (rare in the current market)
- lack of long-term perspective for the site
In practice, however, these cases are the exception.
Conclusion: Photovoltaics is a strategic lever for businesses
Photovoltaics today no longer a pure sustainability issue, but a central component of economic energy supply.
For industry and commerce, this means:
- lower and predictable energy costs
- higher security of supply
- better ESG performance
Companies that invest early or use suitable models secure long-term competitive advantages.
